A great example of the power of imagery is when a camera travels to a different planet, allowing us to see something we normally would not be be able to see.

The above image is an excellent perspective captured by the High Resolution Stereo Camera (HRSC) on board ESA’s Mars Express spacecraft showing a section of the Ophir Chasma, a northern part of the Valles Marineris canyon.

The cameras on the Mars Rovers are mounted at eye-level. This was done to provide the closest approximation to a person actually walking on the surface.
